archicad interrupted logout

Patrick M — Tue, 30 Jun 2026 10:07:12 GMT

anyone else notice, if you walk away from your computer for an hour or two, particularly on mac when it tries to 'go to sleep', it tries to shut down archicad? I've also left ac open over night (yeah, I know thats bad, and I don't take my own advice on this and so many other things) to find that ac is closed the following morning, with no bug report or crash recovery...

Operating system used: Mac Apple Silicon

So, do you consider this a bug?

Should macOS not be able to shut down Archicad? When it shuts it down, is there work or data lost the next morning? (If you did not save before leaving Archicad.) Is there an Autosave available next morning?

it's definitely a combination of bug + user error.
Obviously, there is no reason or excuse to leave a file open over night; and even worse, forgetting to save before calling it quits for the day. This is all user error.

And I'm not sure if the OS shutting down Archicad when it 'goes to sleep' is a software feature or bug; but it seems like it shouldn't try to quit archicad.

...
I have seen lost work when shutting down for the day and not saving/closing. That is easily mitigated by simply saving and closing... but I'm only perfect when I direct/criticize/train other people's workflow & protocols; I fall short when in practice on my own 😉

The only times macOS will try to shut down a file are:

File is using too much memory
Install an update

Almost all mac software autosaves their state so the system can do any necessary automatic tasks.

Guess to which group AC belongs to…

I usually close all files before I hibernate my (Windows) PC, but there are times when I've forgotten and left it open overnight. I haven't seen anything adverse so far. macOS issue?

@Eduardo Rolon maybe it is a memory issue... I have 128GB physical memory, and typically have 75+GB free. But I have seen Cineware eating up massive memory caches (even though I never use cinerender). I think I posted about this years ago when my older macs were routinely running out of memory with only a few AC files open, a nd I'd see Cinware taking up 5-10x more memory than Archicad. Doesn't look like its that bad on my compy now:

This one is a mac only issue and I don't think GS can do much about it because of TW.

this happens more on .pln files than on t/w files; at least when I deal with it.

I have not seen the logout but have experienced the situation where I find AC has crashed after waking my MacBook Pro (M1 Max) from sleep. It may also take a change of network to trigger since I usually discover it after taking my computer home from the office.

I am not shutting my computer down, just putting it to sleep, then waking it back up. If this works fine 9 times then it crashes the 10th, that's a bug. If putting my computer to sleep only affects Archicad, that's a bug.

Given how long it takes AC29 to open projects, especially TW projects, quitting Archicad every time I'm done woking is huge time-suck. And sleep should work. It's a normal computer thing.

exactly that!

There was an issue a few years ago where Archciad crashed every time a mac went to sleep. That was an identified bug that got fixed. Sounds like this is a similar issue. Back then (2020/2021? and Archicad 23/24?) it was related to a video card issue. Maybe it's a similar bug.

I'll sometimes leave files open for days on end because I'm always coming and going from my computer. Archicad should not be crashing just because we walk away or close the laptop lid.

its likely similar to the missing model view option bug that was 'fixed'... it still pops up

Hi @Patrick M,

Thank you very much for reporting this and for explaining the behaviour in detail. As others have mentioned, we have seen a similar issue related to video cards before, although it was not identical to the one you described.

To help you further, we would kindly like to ask you to reach out to your local support or reseller: https://www.graphisoft.com/en-at/contact/sales/

Through that channel we can investigate the issue in more detail and collect the necessary project and machine information.

Thank you for your understanding.

Kind regards,

Right on cue, this happened to me again today. No change in network, just close the lid, come back a couple days later (after holiday weekend), open lid to find the crash report. I will add that after restarting Archicad my teamwork project opens in offline mode. This is also common.

I will send this Graphisoft Tech Support today.

in this instance, my computer did not even "sleep". Laptop was open, I simply left to take my kid to a dentist appointment. was gone about an hour and a half. Came back; screen saver not on, computer not asleep. But archicad seems to have been attempting to shut down/log out.

Re: archicad interrupted logout

That doesn't look like Archicad trying to shut down.

It looks like your operating system trying to shut down, but it can't because Archicad is open.

I'd be looking in your operating system settings.

Barry.

yesterday, worked 4 hours, took a lunch break... came back and didn't notice the file had closed/quit. opened the file today, all work was gone. My error in not saving. I was certain I had, but I guess not. No reason to expect the is 100% bug and not at least 15% user error.

Re: archicad interrupted logout

Laszlo Nagy — Fri, 10 Jul 2026 20:17:04 GMT

There was not even an AutoSave file you could open?

Re: archicad interrupted logout

SeaGeoff — Sat, 11 Jul 2026 01:02:43 GMT

There is an acknowledged bug causing wake-from sleep crashes. So maybe stop blaming users or their operating systems. Most of us know when it's Archicad that's causing our problems.

I received some good tech support from Graphisoft on this issue. Find my report here:
